The interest for the protection of the night sky from light pollution is growing every day. A global scale periodic monitoring of the situation is necessary. This site offers research on satellite monitoring of the artificial night sky brightness and the stellar visibility. They measure the upward light flux of sources on the Earth surface based on DMSP satellite data and then they compute the effects on the night sky modelling the light propagation in the atmosphere. Some excellent pictures and research. This has been added to Astronomy Resources Subject Tracer™ Information Blog.
